Bazil is a simple fight. He has only two guards, a Defias Insurgent and a Defias Inmate. It is possible to pull the Inmate away, though this requires skill. If you manage to do so, however, Bazil comes with only one guard.

Being a dual wielder, Bazil can hack up your tank pretty quickly, so be sure to put as many debuffs as possible on him, especially ones that hurt DPS. Bazil is tough, but shouldn't be too much trouble for a well prepared group.
